E LECTRlCALLY-HEATED SOLDERING-IRON;

SPECIFICATION forming part of Letters Patent No. 757,670, dated April19, 1904:.

Application filed May 6, 1903. Serial No. 155,820. (No model.)

To all whom it may concern: I

Be it known that I, ALFRED O. MoCLosKEY, a citizen of the United States,residing in the city and county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inElectrically-Heated Soldering-Irons, of which the following is aspecification.

This invention relates to an improvement in electrically heatedsoldering irons, and its object is to provide means whereby the heatingof the soldering cylinder or iron is facilitated, and also to providemeans whereby the working parts of the device are protected from theaction of the acid fumes which are generated in the operation ofsoldering.

As illustrated, my invention is applied to a device applicable to thepurpose of soldering caps to the tops of cans, but it will be understoodthat it may be employed in connection with a soldering iron suitable forother purposes and in which the soldering iron is of different shape orcontour.

The invention resides in the combination.

and arrangement of parts hereinafter set forth in the specification anddrawings, and specifically pointed out in the claims.

In the drawings, Figure 1 is a side elevation, and Figure 2 is alongitudinal sectional View.

Referring to the drawings, r p

1 designates a heating iron provided with a heating core 2, the saidcore being heated by means of the electricity resisting coil 3 the saidcoil being connected to the electric con ducting wires 1 and 5, asclearly shown.

No attempt will be madeto describe the electric heating device ingreater detail, because it is old and well known, and its details ofconstruction constitute no part of my invention.

Secured to the heating iron 1 is the soldering cylinder or iron 6, thesaid heater and soldering cylinder being connected by a screwthreadedconnection 7 The soldering cylinder or iron is, as shown, cylindrical inform and its lower end is hollowed out to form a space 8, and also theoperating lower edges of the soldering iron which are beveled in themanner clearly shown in Figure 2. The upper end of the solderingcylinder or. iron is provided with a flange 9 which surrounds the lowerend portion of the heating iron 2.

Slots 10 are provided upon opposite sides of the soldering iron, thesaid slots being provided for the purpose ofallowing the escape of thegases and acid fumes from within the hollowed out space in the lower endof the soldering iron, and also for the purpose of permitting movementof the U- shaped frame 11, with respect to the soldering cylinpreventaccess of acid fumes to the working parts of the device.

In order to still further prevent the access of acid fumes to the lowerend of the heating iron and to the region of the connection between saidvheating iron and the soldering iron, I have provided a packing 13,which consists of the circular metallic flat ring 14, located upon thetop of the flange 9, and having a depending flange15 arranged at rightangles to the plane of the ring 1 1, as clearly shown. The said flange15 occupies a position between the upper edge of' the flange 9 and thebody of the heating iron.

1 Located between the lower edge of said flange 15 and the upper edge ofa shoulder 16, which is formed upon the inner surface of the flange-9,is a packing 17 which may consistof any suitable material, preferablyasbestos. It will be obvious that by reason of the separating portion ofmetal 12 and the packing de vice 13, it is impossible for the fumes ofan acid employed in the operation of soldering to enter between thesoldering cylinder or iron and the lower edge of the heating iron. TheU-shaped frame 11, previously referred to, as

bent to U-form, the upwardly extending leg:

thereof being connected to the opposite sides of a ring 18, surroundingthe heating iron, as clearly shown in each of the figures of thedrawings, and adapted to slide upon said heating iron.

Secured to the lower side of the U-shaped frame 11 in any suitablemanner, is a pointed device 19 for holding the caps down upon the topsof the cans during the soldering opera tion, in the usual and well knownmanner.

In order to hold the U-shaped frame 11, the ring 18 and the pointed capholder 19 down in the projected position illustrated, the springs 20 areshown which are connected at their upper ends to the hooks 21 secured tothe ring 18, and at their lower ends to lugs or projections 22,extending outwardly from the cylindrical soldering iron.

As illustrated, the hooks 21 are made separately from and are attachedto the ring 18, but it is obvious that the said hooks may be madeintegral with the said ring. It is also obvious that the wire springs 20may be located at a greater or less distance from the soldering cylinderthan is shown in the drawings.

It is evident that by the continued use of the device, the operatingedges of the soldering iron become worn and, therefore, shortened, and,in order that the lower part of the U-shaped frame may always occupy theposition substantially as shown with respect to the lower end of saidsoldering iron, means are provided for adjusting the said U shaped framewith respect to the soldering iron from time to time.

This means consists of the adjustable stops 23 secured to the oppositesides of the U- shaped frame, by means of screws 24 which pass throughany one of the series of openings 26 shown in the opposite sides of thesaid U- shaped frame 11.

In the operation of using the device, an elec-. tric current is passedthrough the resistance coils 3, whereby the temperature of the heatmgiron is raised to the desired point, such heat being conducted to thesoldering iron 6, the flanges 9 facilitating very materially the heatingoperation.

The caps are placed upon the tops of the cans in connection with acircular piece of solder in the usual manner, after which the holdingpoint 19 is placed upon the center of the cap, whereupon the solderingiron is moved into contact with the cap, and with the top of the can attheir junction.

The heated iron melts the solder and one or more rotations of thesoldering iron distributes the solder and firmly secures the cap to thetop of the can, forming an air-tight connection between the two parts,after which the soldering iron is removed to another can, the cap beingheld upon the can until the solder cools or sets in any suitable orconvenient manner.

It is to be understood that the necessary acid is employed in the usualmanner.

Having thus described my invention, I claim 1. The combination of anelectrically heated heating iron, a soldering head provided with ahollowed out lower end, a partition of metal separating the space formedin the lower end of the soldering iron from the lower end of the heatingiron, and means for connecting the heating iron and the soldering irontogether.
